Hi Anshum,

while?
The answer is yes. I have tried to keep a singleton instance of
IndexSearcher open across web requests.
Regarding to your advice, I have tried to re-open the IndexReader that is
associated with that IndexSearcher
public void deleteById(String id) throws IOException {
IndexWriter writer = IndexWriterFactory.factory();
try {
writer.deleteDocuments(new Term(Configuration.Field.ID,
String.valueOf(id)));
writer.commit();
IndexSearcherFactory.reload();
} catch (ArrayIndexOutOfBoundsException e) {
// CHECK ignore this. Can happen if index has not been built yet
} catch (IOException e) {
System.out.println(e);
}
}
Here is how IndexSearcherFactory#reload is defined
public static void reload() throws CorruptIndexException, IOException {
Set<Map.Entry<String, IndexReader>> set = readers.entrySet();
for (Map.Entry<String, IndexReader> entry : set) {
readers.put(entry.getKey(), entry.getValue().reopen(true));
}
}
However, it does not work either.
Is there any way to debug this situation?
Thanks,
Dinh
